u '5 Claims. This invention relates to an air filter for poultry brooders and the like and it consists intheconstructions, arrangements and combinations herein described and claimed.

It is an object of the invention. to provide a v filter device of such construction as to be readily installed in the air inlet or vent of a hover brooder.

It is also an object of the invention to provide ill a novel filter of a portable construction embodying filter material and a reservoir for medicines so that the air passing into the hover will not only be cleaned of dust, but will be impregnated with vapors from the medicine. It is a still further object of the invention to provide a filter of the character stated in which the amount of air passing into the hover may be regulated.

Additional objects, advantages and features of an invention will be apparent from the following description and accompanying drawing, in which Figure 1 is a vertical sectional view of my filter installed in'the air inlet of a hover brooder,

Figure 2 is a similar view partly in section, of w a modified form oi the filter,

Figure 3 is an elevation of another form of the device, partly in section,

Figure 4 is a similar view of a still further form of filter.

am At present, ventilation of brooders is accomplished by the use of rotary impellers, forcing or drawing air from the exterior to the interior of the brooder, and it has been found that the air thus delivered tothe brooder contains a great deal of dust and foreign matter injurious to the health of the chicks.

The air intake is ordinarily at the apex of the roof of the brooder, as shown at Ill, which includes a downwardly directed chimney II, as indicated in Figures 1, 3 and 4, or an upstanding chimney, as shown in Figure 2.

The impeller may be positioned in the chimney H so as to draw the air inwardly as at H '(Figure 1) or blow the air into the brooder as indicated at H3 in Figure 2.

Attention is first invited to Figurev 1 of the drawing, wherein the filter I4 is shown. as a cylindrical drum having an axial aperture I5- defined by a collar I6. The collar I6 extends upwardly in the drum It for a short distanceand downwardly below the bottom wall of the drum,

.the latter having snug seating engagement in the chimney ll, so that the filter will be firmly retained against accidental dislodgement.

Upon the upper end 01 the collar Hi there is secured a spider H for support of a combined closure and valve l8, as will be described. The combined closure and valve, in the present instances, consists of a circular cover member I9, 5 of a diameter slightly greater than that of the drum and upon the under face there is provided a collar 29 of a depth slightly more than one half the depth of the drum Hi and of a diameter considerably less than the diameter of the drum Id. Thus the collar 20 lies spaced inwardly and concentric with the wall of the drum, as shown at El.

A wire screen filter retainer 22 is secured upon the bottom wall of thedrum Ill, 'disposedvertically and of annular form and of a diameter to permit readyfpassage of the collar 25 there around.

The cover member it has a wing bolt 23 revolubly mounted through its axial center, the lower end being screw threaded for engagement with a threaded aperture in the spider i'l. A helical spring 213 is mounted upon the bolt 23, inter-- posed between the cover plate iii and the spider ii, the spring acting to maintain the cover plate in adjusted position with respect to the upper edge of the drum, thereby regulating the amount of ,air passing into the drum.

Any suitable filter material 25 may be placed in the retainer 22, and the drum may be provided with any desired medicament with which it is desired to treat thephicks housed in the hover,

.or it may be any substance which might tend to purify the air to be discharged into the hover. An overflow vent 26. is formed in the wall of the drum at any suitable height.

The operation will be clearly apparent, but briefly stated, the cover I9 will be adjusted to regulate the amount of air entering the drum, by means of the screw 23, the passage of air being indicated by arrows, drawn thus, by operation of the impeller l2. It will be apparent that the air will be brought into contact with medicament and drawn through the filter material and finally will pass downwardly through the chimney l6 and discharge into the hover; Obviously, the degree of medicated air may be regulatedby'adjustmert of the collar 20 with respect to the level of the medicament. 50

Reference. is now made to. Figure 2, wherein the chimney H is upwardly directed and upon which theIcollar N3 of the drum I4 is fitted. The upper end of the collar l6 has a screen 21 fitted thereto permitting passage of air through 55 the chimney due to suction created by the impeller l3.

An annular retainer screen 22 is provided, as before described, to confine the filter material 25. A conically shaped cover 28 of a size to snugly engage upon the periphery of the drum is provided, the downwardly extended flange 29 being provided with a plurality of circumferentlallyspaced apertures 30. These apertures are cooperable with apertures 3| formed in the wall of the drum l4 and by rotating the cover, the degree of opening between the registering apertures may be varied, thereby regulating the amount of air passing into the drum.

In order that the air may be caused to engage the medicament in the drum, a downwardly dis.- posed annular flange 32' is fixed to the underside of the cover 28, the flange 32 being suitably spaced from the Wall of the drum to permit proper flow of air.

In Figure 3, a simplifi ed form of filter is shown, in which the structure comprises a rectangular box having a collar Ilia of a size to snugly engage within the chimney Ila- The box has a filler opening 33 for the purpose of filling the box with a medicine or oil, as desired; an overflow opening 34 and anysuitable number of rotary air control valves 35 may be installed in the side,

shown at 38, of a diameter to snugly fit within I the chimney H. The wall of the cartridge at opposite sides, is provided with a plurality of vertically spaced apertures 39, and the upper end of the cartridge is flanged as at for receiving a cap 4|, the cap being apertured as at 42 for admission of air therethrough, as will be exmedicament or oil, and obviously, the supply may be replenished by injection through the apertures 39 and 42, if and when found necessary.

The regulation of the'air, in this form is accomplished by'vertical adjustment of the cartridge within the chimney, thereby increasing or decreasing the number of apertures 39 exposed to the atmosphere.

From the foregoing, it will be seen that I have provided portable filter devices which may be readily installed and removed from hovers for cleaning, and which in use, insures entrance of purified or medicated air to the chicks, and in no wise interfere with proper ventilation of the hover.

If desired, any conventional heating means may be employed to vaporize the medicament.

While I have shown and described preferred forms of the filter, this is by way of illustration only, and I consider as my own, all such modifications in structure, as fairly fall within the scope of the appended claims. I

I claim:

1. An air purifying and medicating'device for hovers comprising a receptacle and having means for connection with the air'entrance passage of a hover, an upstanding collar within the recep- 'tacle defining a passage into the hover, the collar extending above the level of a medicament within the receptacle, a filter material within the receptacle and disposed above and around the collar, a cover for the receptacle'adjustable with respect thereto to regulate the passage of air into the receptacle, and means for effecting passage of air through the medicament, filter material and the air entrance passage.
